Principle of blood glucose meter,Use of blood glucose meter

【Introduction】

Blood Glucose Meter, also known as blood glucose monitor, is a portable medical device used to measure glucose (blood sugar) concentration in the blood. It is widely used by diabetic patients to self-monitor blood sugar levels, helping them understand their health status and make appropriate treatment adjustments. A blood glucose meter usually consists of a small electronic instrument and test strips required for blood glucose testing.


Classification of blood glucose meters

1. Home-use blood glucose meter: This type of blood glucose meter is mainly for individual users and is suitable for blood glucose monitoring at home or in daily life. They are typically small, easy to operate, and provide fast, accurate blood glucose measurements.

2. Medical blood glucose meter: Medical blood glucose meter is mainly used in medical institutions, such as hospitals, clinics, etc. Compared with the home-use type, the medical-type blood glucose meter is more professional in terms of accuracy and function, and can meet the higher requirements of clinicians for blood glucose data.

3. Continuous blood glucose monitor: This blood glucose meter uses puncture or non-invasive technology to continuously monitor blood sugar levels and transmit data to external devices or mobile applications in real time. They are suitable for long-term blood glucose monitoring and can provide more detailed and comprehensive data.


Principle of blood glucose meter

The working principle of blood glucose meters is usually based on the reaction of glucose with certain chemical reagents (such as glucose oxidase). The current or light signal generated by the reaction is detected by electrochemical or optical methods, and then the measured value is compared with the standard curve to obtain accurate blood glucose levels.


Use of blood glucose meter

1. Diabetes management: The blood glucose meter is an important tool for diabetic patients to monitor blood sugar. By regularly testing blood sugar levels, patients can keep track of their blood sugar changes and rationally adjust their diet, medications, exercise and other lifestyle to maintain blood sugar within the normal range.

2. Health management: In addition to diabetic patients, some groups also need blood glucose monitoring, such as people with a family history of diabetes, obese people, and patients with certain special diseases. Blood glucose meters can provide timely and effective blood glucose data, helping people detect abnormalities early and take appropriate preventive and intervention measures.


Features of blood glucose meter

1. High accuracy: Modern blood glucose meters use advanced optical, electrochemical or electronic technologies and are highly accurate and reliable. By using test strips or sensors during the test, measurement results can be obtained in a short time and are quite close to professional laboratory test results.

2. High portability: Blood glucose meters are usually small and easy to carry. Whether it is a home-use or portable blood glucose meter, it is convenient for users to conduct blood glucose tests at any time without going to a medical institution.

3. Simple operation: For different user groups, the blood glucose meter has designed a simple and easy-to-understand operating interface and steps, allowing users to easily complete blood glucose tests by themselves. Generally speaking, you only need to obtain a blood sample, place it on a test strip or sensor, and start the blood glucose meter to get the measurement result.

4. Data storage and analysis: Many modern blood glucose meters have built-in memory or are connected to mobile applications, which can record and track the user's blood glucose data. These devices can generate blood sugar curves, trend charts, etc. to help users understand their own blood sugar changes more intuitively.


Advantages of blood glucose meter

1. Rapid detection. After blood collection, the test results are displayed quickly and accurately, and the results are stable.

2. The detection is accurate. The smart blood glucose meter uses biological enzyme siphon test paper reaction technology, combined with electrochemical biosensing technology, to meet international data accuracy requirements.

3. Intelligent identification. Automatic code reading and recognition eliminates the need to manually enter the test strip code. It automatically turns on when inserting the test strip and automatically shuts down when the test strip is pulled out, making it easy for elderly patients to use it and saving power.

4. Painless blood collection. Blood glucose testing can be completed with only a minimal amount of blood collection. Avoid having your fingers riddled with holes due to excessive blood collection.

5. Clear display. The large screen displays the test results, fully considering the elderly and patients with blurred vision, and they can see clearly without wearing glasses.

6. Synchronous recording. The blood glucose meter can be connected to a computer at home, and the blood glucose analysis chart can be displayed completely and accurately on the computer. Provide scientific basis for disease development. It can also be bound to the Control Diabetes APP or WeChat. Patients can record blood sugar, blood pressure and other health data at any time through the APP or WeChat, view blood sugar records, and learn various aspects of diet, medication, and exercise.


How to use a blood glucose meter

1. Clean your hands, prick your fingertip with a blood collection pen, and insert the test paper into the blood glucose meter.

2. Use the blood-sucking port of the test paper to suck blood until the entire observation window is filled.

3. The instrument displays the results and automatically stores them.

4. Take out the test paper and properly dispose of the blood collection needle and used test paper according to the instructions.

5. It can be connected to a computer, or bound to the Diabetes Control APP, WeChat, etc., to record and view blood sugar and other health data at any time through the computer, APP or WeChat.


Precautions for measuring blood glucose meter

1. Cleaning and disinfection: Before and after use, attention should be paid to keeping the blood glucose meter clean and disinfected according to the instructions for use. This helps prevent cross-contamination and results accuracy.

2. Blood sample collection: Correct collection of blood samples is crucial to the accuracy of test results. Wash your hands with soap and warm water before collecting. Select the appropriate blood collection site, clean and press it, and then use the needle or puncture provided with the blood glucose meter to collect blood.

3. Use of test strips or sensors: Before using the test strips or sensors, make sure that they are within the validity period and that the outer packaging is not damaged. For a test strip type blood glucose meter, insert the test strip into the instrument and follow the instructions to place the blood sample. For sensor-type blood glucose meters, follow the instructions for proper installation and startup.

4. Follow the instructions for use: Different brands and models of blood glucose meters may be slightly different, so read and follow the corresponding instructions carefully during use. Pay attention to the impact of time, temperature, environment and other factors on the test results.

5. Regular calibration and maintenance: Blood glucose meters usually require regular calibration to ensure accuracy. At the same time, pay attention to replacing batteries, memory capacity, and maintaining the cleanliness and integrity of the equipment.
